Default 48whp and 41tq on fast 102 intake/Tb

well dropped some coin on a fast 102 intake/Tb. And im glad i did. Netted a gain of 48hp/41tq over the stock ls6 intake.Tbh its probably actually a lil more but couldn't get previous dyno graph of the ls6 intake due to a system crash of his dyno so we only had the base pull of the fast 102 to compare to.. Mustang dyno

Next im goin to fix the restriction in the exhaust so i can pull this bad boy to 7k rpm.. Took to the track after and ran a 11.0 wich is a half sec gain in the quarter and 4mph trap speed.

shifting at only 6400 rpm

What intake were you previously running? I know someone posted a 1 hp gain going from a Fast 92 to a Fast 102 on a 383.

dont mind that first weird pull lol.. i dont know wtf that was lmao. That was the first pull with the fast before tuning.. then we got 48/41 after tuning. we actually picked up more if we were to compare the graph of the fast 102 over the ls6 but his system crashed and we lost the previous dyno graphs of the car with the ls6 intake..

I have trouble believing it was all from the intake and TB alone

This has me excited for my future results...going from a stock nnbs truck/tbss intake manifold to a ported lsxRT. Should have results in a week. Nice gains btw and you said it felt like it and then some, good sign.
Rwhp in the 40s also adds up with a 4 mph gain...makes sense.

That seems really high. I would think 15-20 hp over the ls6 would be realistic. No other changes where made?

Would the below graph the one you were talking about. I saved it to my computer along with other Graphs of Dyno Pulls with ORY exhaust, to study the Torque Curves of car's Dyno'ed with ORY's. Definite curve shape that makes it easy to spot Exhaust is a problem with making max power.

By the way my research on power number difference on PEAK Numbers between number's difference range between a Mustang Dyno compared to Dynojet numbers between the one Mustang in my area compared to the 3 Dynojets in my area are 12.5% low end , 13.0% mid, 14.0% high.
I always Dyno and Tune on a Mustang, Then do some pulls on a Dyno Jet for comparison. I all ways quote Mustang numbers as they are lower. Dyno numbers don't beat you, an low ones give you an excuse for losing. We want say what happens if your car beats the car with higher dynojet numbers...LOL


To be on the safe side for comparison purposes to others with similar setups dynoed on Dynojet dyno's, use the 12.5% percent increase for comparison.

382.0 HP Mustang before + 48 HP gain after TB and Fast Intake = 430 HP. Add 12.5% low end percentage increase numbers for comparison to what engine numbers would look like on a Dynojet and they would be 483.75 HP for Dyno too Dyno comparison numbers.



PS: Remember, I get to play my 75yr old man "Stupid is as Stupid does" card on all my posts. No beating up on the Old Guy....Now : Just Educate him if he's wrong,,, nicely as he's trying to learn!

Great to see results! Awesome run. After you open the exhaust up you should get a 6 sec. 1/8 & a 10. Great job man!

just intake/Tb.. i too was only expecting 15 hp but il take it. u wo t hear me complaining lol. TBH i really care bout he half second and 4mph increase at the track. im not too big on dyno numbers other then for tuning . 11.53 @118with the stock ls6 and now 11.07 @ 122 with the fast. All from just swapping the intake/Tb...

i never lchecked tbh but i am gonna start writing it down on each timeslip. for situations like this..This we i can have a more accurate comparison when it comes to the track.. im sure there was some difference wich played a factor .
